Few of the fans who attended Sunday’s NASCAR race at Chicagoland Speedway were as excited to be at the track as 9-year-old Wyatt Zender of Deming, Wash. Wyatt and his family were guests of Kasey Kahne and his sponsor, Great Clips.

It’s not a stretch to say that Greta Oberhofer is alive thanks to the genetically modified cell therapy called CAR-T. At three and a half months old, she was diagnosed with acute lymphoblastic leukemia, or ALL, an aggressive blood cancer.

Kasey Kahne's #5 Great Clips Strong Against Cancer Chevrolet SS will have a different look this weekend at the Chicagoland Speedway. Children from Seattle Children's Hospital had the opportunity to create a design for Kahne's car.
